In a fit of rage, Terry throws a ball into the air with a velocity of 100 m/s. At the highest point of it's trajectory, what is
Oxana [17]

From the moment it leaves Terry's hand ... all the way up and then all the way down ... until the moment the ball hits the ground, its acceleration is 9.8 m/s^2 downward. That's the acceleration of gravity (on Earth), and gravity is the only force acting on the ball.

By the way ... Terry needs to control his rage and go get a job as a pitcher for Major League Baseball. That 100 m/s of his is more than double the speed that professional pitchers typically deliver !

Optical tweezers use light from a laser to move single atoms and molecules around. Suppose the intensity of light from the tweez
Zanzabum

(a)  3.3\cdot 10^{-6} Pa

The radiation pressure exerted by an electromagnetic wave on a surface that totally absorbs the radiation is given by

p=\frac{I}{c}

where

I is the intensity of the wave

c is the speed of light

In this problem,

I=1000 W/m^2

and substituting c=3\cdot 10^8 m/s, we find the radiation pressure

p=\frac{1000 W/m^2}{3\cdot 10^8 m/s}=3.3\cdot 10^{-6}Pa

(b) 4.4\cdot 10^{-8} m/s^2

Since we know the cross-sectional area of the laser beam:

A=6.65\cdot 10^{-29}m^2

starting from the radiation pressure found at point (a), we can calculate the force exerted on a tritium atom:

F=pa=(3.3\cdot 10^{-6}Pa)(6.65\cdot 10^{-29} m^2)=2.2\cdot 10^{-34}N

And then, since we know the mass of the atom

m=5.01\cdot 10^{-27}kg

we can find the acceleration, by using Newton's second law:

a=\frac{F}{m}=\frac{2.2\cdot 10^{-34} N}{5.01\cdot 10^{-27} kg}=4.4\cdot 10^{-8} m/s^2

Which of these is most directly related to the mass of an object?
Anuta_ua [19.1K]
Weight is directly related to mass, but it also
depends on the local gravity.

Acceleration is directly related to mass, but it also
depends on the net force acting on the mass.

<span> <span> </span></span>Volume is directly related to mass, but it also
depends on the density of the object or sample.

Inertia is directly related to mass, and is completely determined
by the mass.  It doesn't depend on anything else, so this may be
the best choice.
